Abstract

An electric treadmill with a folding mechanism includes a handrail frame pivotably mounted at both sides of the front end of the base frame. A guide plate having a sliding groove, two link plates, and a positioning plate attached to the handrail frame are provided between both sides of the base frame and the handrail frame. The guide plate is connected to a sliding support of a ground-touching roller. The sliding support is pivotably coupled to the bottom of the base frame. According to the assembly of the above-mentioned components, when the base frame is lifted in a folded position, a slide pin of the link plates is movable in the sliding groove of the guide plate until the base frame is folded in an upright position.

Claims

1. An electric treadmill with a folding mechanism, the treadmill having a continuous moving belt positioned around a base frame and driven by an electric motor, a handrail frame being mounted at both sides of the front end of the base frame, the bottom of the front end of the base frame being provided with a front support frame driven by a lifting motor for adjusting the supporting angle of the base frame, several ground-touching elements being fitted to the bottom of the rear side of the base frame,

wherein a guide plate having a sliding groove, two link plates, and a positioning plate attached to the handrail frame are provided between both sides of the base frame and the handrail frame;

wherein the guide plate is connected to a sliding support of a ground-touching roller;

wherein the sliding support is pivotably coupled to the bottom of the base frame, whereby according to the assembly of the above-mentioned components, when the base frame is lifted in a folded position, a slide pin of the link plates is movable in the sliding groove of the guide plate until the base frame is folded in an upright position.

2. The electric treadmill with a folding mechanism as recited in claim 1, wherein the link plates are pivotably secured to corresponding pivots of the base frame.

3. The electric treadmill with a folding mechanism as recited in claim 1, wherein an elastic element is interposed between the guide plate and a handrail positioning plate.
